Post-operative management and follow-up of surgical treatment in the case of rectovaginal and retrocervical endometriosis.
2020
Abstract Introduction Deep infiltrating endometriosis (DIE) affects between 3.8% and 37% of all endometriosis patients, mostly affecting rectovaginal septum or retrocervical space and characterized by the severe endometriosis-related complaints. Nowadays, generally managed with surgery. However, this is associated with a risk of postoperative complications. To better evaluate intra- and postoperative complications and outcomes for rectovaginal (RVE) and retrocervical endometriosis (RCE), the preoperative management should be accurately described and compared. Methodology This is a cohort retrospective study performed at the Endometriosis Centre of Charité-University Clinic, Berlin. 34 patie…

Demography and Economic Growth in Spain: A Time Series Analysis
2003
In this paper, advanced time series econometric tools are employed to test the existence of relationships among demographic and macroeconomic variables in Spain along the 1960-2000 period. Annual data for the total fertility rate, infant mortality rate, per capita gross domestic product and wages are used in the empirical analysis. We first examine the bivariate Granger causality to look for short run relations. Then, a multivariate cointegration analysis is carry out, showing that two long run relationships among the variables exist with statistically significant coefficients. From these cointegration vectors, the vector error correction model is estimated to test the endogenous or exogeno…
Pension Schemes and Falling Birth-Rates: Change in Customs or Microeconomic Optimization?
2004
In this paper, we develop an overlapping generations model where fertility is endogenous. The utility of the parents is a function of the number of their children, and each child implies two types of fixed costs: the financial cost and the cost in terms of time. A "pay-as-you-go" pension scheme introduces an externality in that the number of children will be fewer than optimal because their favorable impact on the level of pension income is not taken into account. First, we define the competitive equilibrium dynamics and the steady state. This allows comparisons with the optimal stationary state, a notion which generalizes the golden rule. Two instruments, pensions and child benefits, are n…
Parity and number of repeated doe-litter-separation treatments affect differently the reproductive performances of lactating does.
2010
[EN] Using data from three different experiments, the effects of oestrus synchronisation by doe-litter separation (DLS), applied 48 hours befare artificial insemination from day 9 to day 11 post partum, on productive performance of free nursing rabbit does and their litters in relation to parity and number of successive DLS treatments were evaluated. lnitially, 200 New Zealand White does of different parity were homogeneously and definitively distributed in two groups (DLS and Control). On the whole, DLS improved fertility (+23.9%, Ps0.001 ), but reduced the growth of young rabbits from day 9 to weaning (-1.7 g/d, Ps0.01) and their weaning weight (-38 g, Ps0.01) at day 35. DLS also increase…
Iedzīvotāju skaita samazināšanās un jauniešu emigrācija Latvijā un Lietuvā
2018
Maģistra darba mērķis ir aprakstīt un analizēt demogrāfiskās tendences iedzīvotāju migrācijā, novecošanā, populācijas sarukšanā, intelektuālā darbaspēka emigrācijā un izvērtēt šos kritērijus Lietuvā un Latvijā. Kādas ir dažādo demogrāfisko parādību definīcijas un to atšķirības un kā tās tiek pielietotas Lietuvā un Latvijā salīdzinājumā ar pārējo pasauli un Eiropas Savienību? Un kāda ir Lietuvas un Latvijas jaunatnes motivācija dzīvot, strādāt un veidot ģimenes savā dzimtenē? Ko veicina augsts negatīvās migrācijas, iedzīvotāju skaita samazināšanās un novecošanas rādītājs Lietuvā un Latvijā un kāpēc tas ir tik svarīgs jautājums? Darbā tiks analizēti notikumi no 90. gadu sākuma līdz mūsdienām …
Global, regional, and national mortality among young people aged 10–24 years, 1950–2019: a systematic analysis for the Global Burden of Disease Study…
2021
Background Documentation of patterns and long-term trends in mortality in young people, which reflect huge changes in demographic and social determinants of adolescent health, enables identification of global investment priorities for this age group. We aimed to analyse data on the number of deaths, years of life lost, and mortality rates by sex and age group in people aged 10–24 years in 204 countries and territories from 1950 to 2019 by use of estimates from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019. Methods We report trends in estimated total numbers of deaths and mortality rate per 100 000 population in young people aged 10–24 years by age group (10–14 y…
Global age-sex-specific fertility, mortality, healthy life expectancy (HALE), and population estimates in 204 countries and territories, 1950–2019: a…
2020
Background Accurate and up-to-date assessment of demographic metrics is crucial for understanding a wide range of social, economic, and public health issues that affect populations worldwide. The Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 produced updated and comprehensive demographic assessments of the key indicators of fertility, mortality, migration, and population for 204 countries and territories and selected subnational locations from 1950 to 2019. Methods 8078 country-years of vital registration and sample registration data, 938 surveys, 349 censuses, and 238 other sources were identified and used to estimate age-specific fertility. Spatiotemporal Gaussian…
High-to-low (Regional) fertility transitions in a peripheral european country: The contribution of exploratory time series analysis
2021
Diachronic variations in demographic rates have frequently reflected social transformations and a (more or less evident) impact of sequential economic downturns. By assessing changes over time in Total Fertility Rate (TFR) at the regional scale in Italy, our study investigates the long-term transition (1952–2019) characteristic of Mediterranean fertility, showing a continuous decline of births since the late 1970s and marked disparities between high- and low-fertility regions along the latitude gradient. Together with a rapid decline in the country TFR, the spatiotemporal evolution of regional fertility in Italy—illustrated through an exploratory time series statistical approach—outlines th…
Personality Traits Increasingly Important for Male Fertility: Evidence from Norway
2014
We study the relationship between personality traits and fertility using a survey of Norwegian men and women born from 1927 to 1968 (N = 7017 individuals). We found that personality relates to men's and women's fertility differently; conscientiousness decreases female fertility, openness decreases male fertility and extraversion raises the fertility of both sexes. Neuroticism depresses fertility for men, but only for those born after 1956. The lower male fertility in younger cohorts high in neuroticism cannot be explained by partnership status, income or education. The proportion of childless men (at age 40 years) has increased rapidly for Norwegian male cohorts from 1940 to 1970 (from abo…
